Holder and shut off valve for a water flow control device

摘要

An apparatus for mounting a flow measuring device between an input fluid line and an output fluid line has a sleeve with an opening therethrough mounted to a base and capable of reciprocating between extended and retracted positions. The sleeve secures the flow measuring device in the extended position and releases the device in the retracted position. A cam secures the sleeve in the retracted or extended positions. A valve is fixed to the sleeve such that, when the sleeve is in its extended position, fluid flows around the valve and through the sleeve. When the sleeve is in its retracted position to remove the flow measuring device, the valve seats on the input fluid line.
